Sorry, but in my IBMPC.C for MicroEMACS 3.8g was bug. Here's John Maline's
mail to me. Thanks John.

->I think I've found a problem in your combined CGA/mono/EGA driver.  You
->define the character pointer 'buf' in the initialization function, but its
->value is never set (or I missed it).  Therefore, when you use it as a buffer
->for the peek() and poke() calls, you are changing a byte in some random
->memory location.
->This could be fixed by changing the declaration to something like:
->char *buf = "x";
->This would make 'buf' point to a known safe place.
